8 Claims.

An object of this invention is to provide a wire working tool of thiskind which is so constructed that a single or a plurality of strands ofwire may be securely clamped within the device-so that the wire can'bepulled or otherwise worked, such as twisting or the like. V

Another object. of this invention is to provide an exceedingly simplewire twisting device which is so constructed that the wire will befirmly held within the device while a portion of the device may berotated so as to twist a plurality of 5 strands of wire together withoutrequiring th ends of the wire to be relatively long;

A further object of this invention is to provide a device of this kindwhich can be used for either working wire, rods, or other elongatedarticles. The above and various'other objects and advantages of thisinvention will in part be described and in part be understood from thefollowing detailed description of the present preferred embodiment,thesame being illustrated in 2.5 the accompanying drawing wherein:-

Figure 1 is a detail sideqelevation of a device constructed according tothe preferred. embodiment of thisinvention.

Figure 2 is a longitudinal section partly in 30 detail of the deviceshowing a pair of wire strands secured therein.

' Figure'3 is a sectional view taken on the line 33 of Figure 1.

Referring to the drawing wherein like numerals 85 of reference designatecorresponding parts 45 vided with a crank handle 14 which is suitablysecured to the inner end of the shaft and preferably, a washer oranti-friction element 15 is interposed between the hub of the handle 14and the inner end of the housing 10.

A head 16 is carried by the outer end of the shaft 12, and this head 16has an opening 17 extending transversely therethrough within which awire clamping member, generally designated as 18, is rotatable. Thiswire clamping member ,55 18 comprises a transversely extending shaft 19arm 11.

provided on the periphery thereof with a recess 20which is disposed inalinement with the bore 13 so that when the shaft 19 is rotated to aposition where the recess 20 registerswith the opening 13, a wire or rodmay be readily passed into .the bore 13.

A lever 21 is carried by one end of the shaft 19, and this lever 21 hasa flange 22 integral therewith which is adapted to engage one side ofthe head 16 for holding the shaft 19 against movement in one directionthrough the head 16. A cotter pin 23 extends transversely through theopposite end of the shaft 19 and engages against a washer 24 and coactswith the flange 22 to holdthe shaft 19 against lateral movement in thehead 16 while permitting rotary movement.

A lug 25 provided with a hole 26 is carried by the shaft 19 andpreferably this lug 25 is integral with the shaft 19 and with the lever21 and the flange 22. This lug 25 with the hole 26 provides a means"whereby additional leverage may be placed-on the shaft 19 so as to moretightly clamp a wire within-the head 16. Preferably, the head 16 has arecess 27. within which the wire is adapted to be forced upon turning ofthe clamping member 18 in the head 16. A stop lug 28 is carried by thelever 21 and is adapted to engage a fixed lug 29 carried by the head 16so as to stop the rotation of the shaft 19 when it is turned into wirereceiving position. The head 16 is provided on one side thereof with apair of claws 30, which claws provide means whereby the wire may bepulled by disposing the wire between the claws 30 and using the outerend of the arm 11 as a fulcrum and rocking the device on this In the useand operation of this wire pulling and twisting device, the wire W ispassed through the bore 13 after the lever 21 has been rocked toinoperative position or the position shown in Figure 1. This lever 21can then be rocked forwardly or outwardly toward the outer end of thehead 16 and if the wire or other article disposed in the bore 13 isrelatively stiff and will not readily be forced into the recess 27, arod (not shown) may be passed through the opening 26 of the lug 25 andadditional leverage applied to the clamping member 18. If it is desiredto twist the wire W after the clamping member 18 has been turned toclamping position, the casing 10 may be grasped in the hand and thecrank handle 14 then turned in the desired direction. During thisoperation, the arm 11 will also act as a guard so as to prevent theclaws 30 from injuring the hand of the operator.

It is, of course, understood that various changes and modifications maybe made in the details of construction and design of the abovespecifically described embodiment of this invention without departingfrom the spirit thereof, such changes and modifications being restrictedonly by the scope of the following claims.

What is claimed is:-

1. A device as set forth comprising a casing, a shaft journaled in thecasing having a bore therethrough, a crank handle secured to one end ofthe shaft, a head on the other end of the shaft having a bore aliningwith the bore in the shaft, and means carried by the head for reducingthe bore in the head at one point and thereby binding an article in thebore of the head.

2. A device as set forth comprising a casing, a shaft journaled in thecasing, a crank handle secured to one end of the shaft, a head on theother end of the shaft, said shaft and head having a bore therethroughto receive a portion of an article to be twisted or clamped, and meansextending transversely through the head for binding an article disposedin the bore of the head.

3. A device as set forth comprising a casing, a shaft journaled in thecasing, a crank handle secured to one end of the shaft, a head on theother end of the shaft, said head and shaft having a bore therethrough,a transversely extending shaft carried by the head, said latter shafthaving a recessed portion adapted to register with the bore in the headupon rotation of the latter shaft to inoperative position, and anoperating lever carried by one end of said latter shaft.

4. A device as set forth comprising a casing, a shaft journaled in thecasing, a crank handle secured to one end of the shaft, a head on theother end of the shaft, said head and shaft having a bore therethrough,a second shaft extending transversely through the head and partiallyintersecting the bore through the head, said second shaft having arecessed peripheral portion whereby upon turning of said second shafttoinoperative position, an article may be freely passed into the bore ofthe head, an operating lever carried by one end of said second shaft,and coacting means carried by the lever and the head to limit therotation of the second shaft.

5. A device as set forth comprising a casing, a shaft journaled in thecasing, an operating handle secured to one end of the shaft, a head onthe other end of the shaft, said head and said shaft having a boretherethrough, a second shaft extending transversely through the head andpartially intersecting the bore in the head, said second shaft having aperipheral recess whereby upon turning of the second shaft toinoperative position an article may be freely passed through the bore inthe head, an operating lever carried by one end of said second shaft, alug carried by the lever, a projection carried by the head and disposedin the path of said lug to limit the turning of said lever, and an armcarried by the casing in offset relation thereto and extending forwardlythereof to permit rocking of the casing for pulling of an articledisposed within the head.
